What is the main advantage of Low Earth Orbit (LEO) satellites?

• A. Constant coverage of the Earth's poles
• B. High bandwidth speed and low latency
• C. Extensive range compared to GEO
• D. Less susceptible to interference

Answer: (B)

The main advantage of Low Earth Orbit (LEO) satellites is that they provide high bandwidth speed and low latency. LEO satellites operate at altitudes ranging from about 160 to 2,000 kilometers above the Earth's surface, which is significantly closer than geostationary satellites that orbit at approximately 35,786 kilometers. This proximity allows for faster data transmission, resulting in reduced delay or latency when compared to satellites in higher orbits.

Moreover, the high bandwidth capabilities of LEO satellites support a wide range of applications, including broadband internet services and real-time communications, making them particularly well-suited for fulfilling the growing demand for fast and reliable connectivity. The lower latency is especially critical for applications that require real-time interaction, such as video conferencing, online gaming, and financial transactions, where delays can have a noticeable impact on user experience.

In comparison, other options present advantages that might not be as pronounced for LEO satellites, such as pole coverage or susceptibility to interference, which are less significant factors in determining their primary benefits.
